The present invention relates to a kind of liquid braking device for motor vehicle.Have for liquid braking device described in each wheel
The dump valve into valve and switchably designed, wherein, brake pressure pipeline is provided with the downstream for entering valve, passes through brake pressure
Pipeline makes to enter valve and dump valve mutually couples, and brake pressure pipeline is oriented to the work of the brake block of the friction brake of wheel
Plug.The hydraulic storage for being used for storing hydraulic fluid is provided with the downstream of dump valve.The invention further relates to one kind to have according to this
The motor vehicle of the liquid braking device of invention.
In order to which liquid braking device is integrated in regenerative system, the quilt of hydraulic fluid in the case where brake pedal is manipulated
The volume of extruding must be imported in hydraulic storage by dump valve, with this so that not formed braking pressure on the piston of brake block
Power.But hydraulic storage produces residual compression in brake pressure pipeline, residual compression presses to car by the dump valve of opening
The piston of the brake block of the brake disc of wheel.This reduces efficiency in terms of the operating energy recovery of regenerative braking.
According to the applicable regeneration brake system of the liquid braking device of the present invention for example by patent document DE 10 2,012 023
Known to 345 A1.According to the document, in order to regeneration braking procedure is in brake activation pedal and to enable after generator be each system
Dynamic device opens pressure dispelling valve so that hydraulic fluid flows out and reduced with this braking pressure in wheel drag from wheel drag
Power.So that the braking moment of hydraulic pressure will not be formed as the total braking force square for additionally including generator torque.
By the A1 of patent document DE 10 2,012 203 779, it is known that in pure regeneration or regeneration braking, braking
Brake pressure in the brake circuit of system is construed as limiting the relevant pressure of the memory size for the brake circuit.This passes through control
The wheel dump valve for making the brake circuit occurs so that brake fluid is braked back by wheel dump valve from main braking cylinder and first
Moved in the memory size of road direction brake circuit.
The technical problems to be solved by the invention are, avoid foregoing because hydraulic storage is to the piston of brake block
Loss in efficiency caused by reaction.

In order to brake motor vehicle 1 by regenerative braking operation, motor 5 is switched to generator operation by computing device 4.
Computing device 4 can be that this is for example designed as control device.Computing device 4 also passes through control of the signal 19 to liquid braking device 3
Device 6 sends signal, and regenerative braking operation has begun to carry out.Then, control device 6 is implemented following in liquid braking device 3
Control process, to arrange regenerative braking to run as efficiently as possible.Reference picture 2 is illustrated to this.
Liquid braking device 3 is illustrated in greater detail again by taking single wheel 2 as an example in Fig. 2.Relative to member shown in Fig. 1
Part additionally shows brake pedal 20, brake booster 21, master cylinder 22, hydraulic storage 23 and pump 24.By to braking
The brake pedal operation 25 of pedal 2, cause the fluid stream 26 of brake fluid 27 by master cylinder 22 in known manner.Control device
6 are based on or according to signal 19 open position is switched into valve 10 and dump valve 11, make fluid stream 26 from master cylinder 22 with this
Brake pressure pipeline 12 is reached by entering valve 10.Fluid stream 26 flows through at valving 13, passes through the influent of dump valve 11
Press memory 23.Thus, hydraulic storage 23 is accommodated by the manipulation 25 of brake pedal 20 hydraulic fluid that is pressed into master cylinder 22
The volume of body.Hydraulic storage 23 can have spring 28, produced by spring or establish residual compression 29, residual compression leads to
Cross the dump valve 11 opened and apply reaction to brake pressure pipeline 12.Herein by the way that valving 13 is closed, in piston 14
On do not form brake pressure, that is residual compression 29 does not act on piston 14.
Thus piston 14 of the hydraulic storage 23 by residual compression 29 to friction brake 8 is prevented by valving 13
Apply reaction.Reason is the design with reference to the valving 13 described in Fig. 3.
Therefore, Fig. 3 shows to be made by hydraulic storage 23, valving 13 and friction for two trailing wheels HR, HL again
The device that dynamic device 8 is formed.In order to which view is succinct, corresponding dump valve 11 is not shown, because being discharged during regenerative braking is run
Hydraulic circuit application effect during valve 11 is anyway in an open position and not to liquid braking device 3.
Valving 13 has the first valve 30 and the second valve 31.Valve 30,31 can be respectively for example spring respectively
The ball valve of supporting.In other words, valve 30,31 is preferably check-valves.First valve 30, which has, passes through direction 32, described to pass through
Direction 32 orients from brake pressure pipeline 12 to the piston 14 of friction brake 8.Second valve 31, which has, passes through direction 33, described
Pointed to by direction 33 from piston 14 to brake pressure pipeline 12.Can be brake pressure from brake pressure by the first valve 30
Pipeline 12 transmits to piston 14.The brake pressure on piston 14 can be eliminated by the second valve 31.First valve 30 has
Opening pressure 34, open pressure 34 and be preferably greater than 1bar, especially greater than 1.5bar, but be especially less than 10bar herein, be especially less than
5bar.Generally, open pressure 34 and be more than residual compression 29, residual compression 29 is caused by the spring 28 of hydraulic storage 23.Second
The opening pressure 35 of valve 31 is preferably smaller than 1bar, especially less than 0.5bar.
Opening pressure 34 of first valve 30 with more than residual compression 29 and the second valve 31 is with being in reverse to residue
Pressure 29 by direction 33, with this so that residual compression 29 is not being opened during regenerative braking is run although dump valve 11
Acted on to the application of piston 14.Thus prevented by valving 13 because the brake block 15 of residual compression 29 is to friction brake
Extruded in 8 brake disc 17.Thus avoid the caused loss in efficiency that rubs.
For each valving 13, valve 30,31 can be connected on braking by corresponding the first common joint 36
On pressure piping 12.Two valves 30,31 can be connected by the second common joint 37 with friction brake 8.
It is considered merely as being used for displaying principle in Fig. 1 to the valving shown in Fig. 3.Car can be assembled according to the implementation of hydraulic pressure
Wheel 2 at least two or can also be all four friction brakes 8.Threshold pressure valve, that is valve 30,31 can be
The brake pressure pipeline 12 in electronic stability control device ESC or being disposed in fluid pressure line 9 is for example integrated in valve body 7
On, or can also be arranged in caliper 16.The valving 13 does not influence the function of hydraulic storage 23, because valve
Device 13 is not disposed in the flow path of brake pressure pipeline 12.
Each valving 13 is the component of hydraulic pressure, and the component of the hydraulic pressure is arranged on valve body 7 or in valve body 7
Towards wheel on brake piping joint.The component is just opened relative only under the pressure condition for instance in 1bar to 2bar
In the port of wheel, not cause the remaining braking moment on friction brake 8 in this stage.The component is in normal brake application
In also play a role, but due to not causing by driver to be felt in braking for the opening pressure selected by the first valve 30
The obstruction of feel.
The embodiment illustrates how that threshold pressure phase can be provided especially in combination with double brake system by the present invention in a word
The switching device of pass.
